From d513320f1fd013d789516a51823a11dc23a3fd55 Mon Sep 17 00:00:00 2001 From: Felipe Balbi Date: Wed, 11 Apr 2018 10:32:52 +0300 Subject: [PATCH] usb: dwc3: gadget: don't issue End Transfer if we have started reqs In case we have many started requests and one of them in the middle is completed with Missed Isoc, let's not End Transfer as that would result in us loosing (possibly) many more intervals. Instead, let's allow the controller to go through its list of started requests.
